Reaction of the carp Cyprinus carpio L. at different periods of its ontogeny to the action of organophosphorus compounds

Effect of some organic phosphorous compounds on the carp Cyprinus carpio L. in consecutive stages of its development has been studied. The least and most vulnerable stages in carp's development under the action of these compounds have been identified. The gravity of disorders in fish organism on early stages and the degree of pathological changes induced by organic phosphorous compounds have been shown. Embryotoxic and gonadotoxic effect of these compounds has been found.
